#!/usr/bin/env bash
# ============================================================
# 捕鱼/棋牌平台 - 一键部署脚本（Linux 服务器 + Docker）
#
# 用法：
#   bash deploy/deploy.sh
#   PUBLIC_HOST=1.2.3.4:8001 bash deploy/deploy.sh   # 指定客户端访问地址（含端口）
#
# 前置要求：
#   - Linux 服务器已安装 Docker（含 docker compose v2 插件）
#   - 服务器可访问 nuget.org 与 docker hub（首次编译需要联网拉取依赖）
#   - 建议预留 5GB 以上磁盘空间
#
# 脚本做的事：
#   1. 在 dotnet/sdk:8.0 容器内编译发布 7 个 Host（服务器无需安装 .NET SDK）
#   2. 覆盖各服务的部署版 Config/system.json，并把网关下游地址改写为容器名
#   3. 构建 7 个镜像（0524gateway / 0524admin / 0524user / 0524customer /
#      0524chess / 0524fishroom / 0524fishgame）
#   4. 启动全部容器（4 个中间件 + 7 个应用）并做健康检查
#
# 常用运维命令：
#   查看状态：docker compose -f deploy/docker-compose.yml ps
#   查看日志：docker compose -f deploy/docker-compose.yml logs -f <服务名>
#   停止全部：docker compose -f deploy/docker-compose.yml down
